Salt Experiment Scientific Method

I Purpose

Tell the difference between rocks and minerals using crystal system

II Hypothesis

Majority of the samples will be minerals

III Materials

• A paper plate
• Four paper cups (stacked upon each other)
• Table Salt
• Stirring sticks
• Heated water

IV Procedure

• First, pile up the four paper cups on each other
• Second, pour 2/3 of a tablespoon of table salt in the cups
• Third, pour in heated water into the cup
• Fourth, stir the salt and the water into a solution and leave the solution for a day
• Finally, the solution will evaporate and leave crystals

V Data/Observations

We observed by looking at this experiment after letting it rest for two weeks, was that the crystals in the plastic spoon had much smaller crystals than the silver/metal spoon, which contained both large crystals and tiny crystals.

VI CER(Claim, Evidence, Reasoning)

The claim we make of this experiment is that it would be able to make salt crystal. The evidence that we came up with is right in the data and observation list in which says that it formed to create salt minerals. This evidence supports my claim because of how they are alike in many ways such as the conclusion when it turns out to be tiny crystals.
